Nest Doorbell (battery) does not store all videos into media folder

Alright. After some testing and debugging I realized that only some of the events are saved as MP4. Most of them are saved as .GIF.

I don’t really know why some of the MP4 clips are missing, maybe you know?

Another thing is. The event happened at 21.00.34 (9:00 PM), but the thumbnail took 4 minutes to get into the media folder (see image above, where it says 21.04 = 9:04 PM), which probably explains why it gives me a 404 when trying to attach it to my notification.

Do you know why some clips are missing and why it takes so long for the media to become available?

I’ve only had luck once as you can see in the following screenshot:
